To all whom I? may concern.'

Be it known that l, HARRY S. WiLLiAMs, a citizen of the vUnited States, residing at San Antonio, in the county of Bexar and Statel of Texas, have invented certain new and useful Improvements inSectiona-l Rims; and

I do declare the following to be a full, clear,-

and exact description of the invention, suoli as will enable others skilled in the art to which it appertains to make and use the same. Y

This invention relates generally to tire rims, and more particularly to sectional demountable tire rims.

The principal object of the invention is to provide a sectional demountable tire rim with interlocking means which can be readily and easily actuated and the rim sections separated so as to remove a tire from or apply one to the rim with the hands and without the use of tools.

Another object of the invention is to provide a sectional demountable tire rim with interlocking means which cannot become unlocked under the lateral pressure of the tire upon the rim sections.

A further object of the invention is to provide a sectional demountable tire rim with interlockingv means having portions engageable with and held in locked position by portions of the means which clamps the rim upon the felly of a wheel.

l "A still further object of the invention is to generally improve upon rims 'of this character 'by the provisionv of4 a` comparatively simple,'strong, durable and inexpensive construction, one which will be eiiicient and reliable operation, and well adapted to the purpose for which it is designed.

With these and other objects in' view, the

invention consists of the novel features of construction, and thecombination and -arrangement of parts as will be hereinafter fully described and claimed.

In the accompanying drawings r Figure l is aside elevation, partly in secy tion, of a portion of a wheel provided with a rim constructed in accordance with this invention. d l n Fig. 2 isa vertical transverse sectional -view of the wheel taken substantially on the Specification of Letters Patent.' y i =Patebed -lway Application led anuary 19, .1920.

locking members carried by. one of' the rim sectionsbeing shown in unlocked position.

Fig. 7 is a view similar to Figs. 4 and d6 .showing the two rim sectionsseparated. Y

Fig. 8 is a view similar toFig. 4 illustratinga modified form of the invention.

Figs. 9 and 10 are transverse sectional views taken substantially .on the lines '9 9 and 10-10 of Fig.-8.

Fig. llv'is a longitudinalsectional `view taken substantially onthe line Y11-11y `loi l In 'the drawings above briefly described a pair of circular complementary rim sections l and Qare shown. IThese sections'land 2- are provided at their outer 'edgeswith outwardly extending flanges 3 adapted kto bear .l

against the'sides of'aftire A as shownvwlien said sections are brought together; in abut-y ting relation. .l y

y The section l haspivoted thereto on its inner side and intermediate their` ends a numberof pairs' ofspaced levers 4,y the` latter extending transverselyof the, section and having one of their'ends projecting av considerable `distance beyond the inner'edge of `the same. The'other ends of thelevers 4 are provided [with noses 5 engageablevwith the coacting 'locking members carried by the secti0n2.

The section 2 carries a numbero locking members in the form of laterally extending shouldered. lugs 6,'thelatter projecting beyond the inner edgeor` 'thelsec'tionfQL The shoulders 7 of thedngs' .6 ar'e'prefer'ably formed by forming notches in the opposite edges of the same. The lugs 6'are insertible between the pairs of spaced levers-4 when the rim sections.` are vbrought together in abutting relation, and the vshoulders"Zidaure fso positioned Hthat when the levers 4 have ,sections 1 and l2 have ridges at the edges of their inner sidesl 8, so that said links will not accidentally become moved out of this position. Further inward movement of the links is prevented by the abutment of shoulders 9 formed upon the same. When the links are in alinement with each other the ends of the levers 4 to which they are pivoted are separated to theirr greatest extent and the noses 5 at the other ends of the levers will be disposed in .their innermost positions interlocked with the shoulders of the lugs 6. ln order to diseng'age the noses 5 of the levers from the lugs 6, l the links 8 are swung outwardly transversely of the rim sections. j

V'In Fig., 401:, the drawings the rim sections are shown in abuttingrelationcand the levers 4 are shown expandedby means of 'the togglelinks so that their noses 5 are engaged'with the shoulders of the lugs 6.

Inthis position the rim' sections are locked together, and it is .obvious that the pressure' of the'tire on the rim exerted trans'- versely so as to tend to separate the rim secvtions will have no effect upon the interlocking means for the same. ln Fig. ,6 theL toggle links 8 are shown in their outwardly swung position so that the levers 4 are ont of `en 'agement with the lugs 6. ,Vhen the partsof the device arein this position the rim sections are separable. In F ig. 7 the rim sections are shown separated and the construction of the parts carried by each of them is clearly illustrated..

ln Figs. l to 7 ofthe drawings the rim j These ridges are cut away at the portions occupied by the lugs 6 and levers 4 so that these members are mounted liat against the inner sides of the sections.. The lugs 6 are secured to the section 2 by means or" pivots or other suitable fastening elements.

In Figs. 8, 9, l0 and 1l, however, the lug ,6 is shown formed integral with the section 2 andthe section l is recessed as at l0 to `receive it. The l,levers 4 are pivoted to the yseetionl Vin portions of the recess l0. The fends ofuthejlevers which project beyond the inner'edgeoff'the section l and the toggle ,in arecessll arranged in the inner side of Vthe section2. u Y .e

When the demountable rim is placed upon links 8ff`3onnected to these ends are received the "folly F rof a wheel such as shownin Figs; l, 2 and 3 of the drawings, it rests remesa upon the metallic rim R usually disposed upon the telly and has the flange 3 carried by the rim section l bearing against the outstruck flange of said rim R1. The flange 8 carried by the rim section 2 is engaged by lugs L disposed upon bolts B which extend transversely through the telly F. The lugs la are adjustable upon the bolts B by means of nuts N. The lugs L have portions disposed adjacent the toggle links 8 so that they prevent lateral shifting of the latter in addition to clamping the demountable rim upon the fixed rim and folly.

From the foregoing description, taken in fonnection with the accompanying draw- `n s, it will be seen that the objects of the n ention have been effectively carried out. llfhen the demountable rim is oftI of the wheel, the tire may be removed from said demountable rim by the'hands without the use of tools by first unlocking the coacting locking elements carried by the rim sections and then separating said rim sections. It is also obvious that when'the tire is placed upon the demountable'rim and inflated the transverse pressure of the tire upon the rim sections cannot in any way aflect the coacting locking means and separate said sections. The levers forming the locking members carried by one ofthe rim sections extending transversely of the latter and the toggle links being disposed adjacent the .outer edge of the other section and swingin outwardly to unlocked position are prevented from becoming unlocked by means of adjacent portions of the lugs which clamp the rim upon the folly.

' Various changes in form, proportion, and in the minor details of construction may be resorted to without departing from the iuvention as defined in the claims.
